DEVICE FOR REGULATING MOTIVE POWER.

SPECIFICATION forming part of Letters Patent No. 558,724, dated April21, 1896.

Application filed September 10, 1888. fierial No. 285,014. (No model.)

To all whom it may concern:

Be it known that LBRADLEY A. FISKE, of the United States Navy, and acitizen of the United States, have invented a certain new and usefulImprovement in Devices for Regulating Motive Power, of which thefollowing is a specification.

My invention relates to the use of power for moving or operatingmachines or bodies which are capable of movements in two or moredifferent planes, such-for instance, as heavy guns, which require to bemoved horizontally and also vertically, cranes, and other hoisting andconveying apparatus, 650.

The object of my invention is to control the motive power so as to giveall the diiferent movements required for the driven machine or body bythe manipulation of a single arm, handle, or lever, and, further, tocause the movements of the driven body to conform or correspond to thoseof the controlling-arm that is, so that an upward movement of the armwill so affect the motive power as to cause the body to move upward, adownward movement will move the body downward, movements to the right orleft will give similar movements to the body, and oblique movements,when such are required, will cause the body to move in the same obliquedirection.

My invention consists in part in a novel apparatus for communicating themovements of the arm, handle, or lever to the controlling devices of themotive power, whereby the objects above named are accomplished in asimple and effective manner; and, further, my invention consistsgenerally in so combining and arranging a single motor in connect-ionwith a machine or body of the character mentioned and suitable powerconnections that the different movements of such body are all producedby the single motor, as hereinafter more particularly set forth andclaimed.

My invention is especially designed for use in connection with electricmotors; but it is also adapted to be used with fluid-pressure motors, aswill be explained.

In the accompanying drawings, Figure 1 is a view representing a gunarranged to be op'i erated by two electric motors by means of thecontrolling apparatus which forms part of my invention; Fig. 2, a rearview and partial section of the controlling apparatus. Fig. 0illustrates the application of the invention to fluid-pressure motors,and Fig. 4 the arrangement for a single motor provided with two powerconnections.

Referring first to Figs. 1 and 2, A represents a gun, which is pivotedat or upon a carriage B, the carriage being itself placed upon avertical pivot Z; and arranged to be turned by the engagement of atoothed wheel 0 with a stationary curved rack d. The front end of thecarriage has wheels 6 running on a rail f.

An electric motor 0 is provided for elevating or depressing the gun. Theshaft of said motor is geared, by bevel-gears g g, with the shaft of ascrew or worm h, which engages a toothed wheel '5, carrying a pinion 7o,which engages a curved rack Z on the side of the gun. The motor 0 issupported, as shown, upon the side of the carriage. Another electricmotor D, placed underneath the gun, between the sides of the carriage,carries upon its shaft the wheel 0, by which the gun and carriage areswung upon the pivot b.

E is an arm or lever attached, by means of a balland-socket joint on orother universal joint, to a lug or projection 72, extending from theside of the carriage.

Each electric motor is provided with a controlling-switch, which, asshown, is of that well-known form in which two arms 0 0 travel over acircular range of contact-blocks 19, having a central position at whichcircuit is broken, to the motor and the armature stands still, while themovement of said arm in either direction closes circuit in one or theother di rection to the motor and causes the same to run in onedirection or the other.

The switch of motor 0 is operated by-a pinion g on the shaft of arms 0o, with which pinion a rack 1' engages, said rack being carried by anarm 3, and similarly the switch of motor D is actuated by a pinion q,rack 0", and arm .3, said arm 5 sliding through a bearing in the side ofthe carriage. The arm 3, which slides through a bearing 25, supportedfrom the gun-carriage, has at its lower end a cross-head it, having aslot 1 at right angles to the length of the arm, and through this slotthe arm E passes. In line with slot 1:,

but at right angles thereto, isthe slot 0) in the cross-head a of thearm 8, and the arm E passes also through said slot 1;.

The operation of these devices is as follows: If both switches are attheir central position and both motors are at rest, and if it is desiredto raise the breech of the gun, the arm E is raised, and such arm whileit moves through the slot 1; so as not to affect the arm 3 engages withthe side of slot 12 and moves arm 8 so as to turn the switch-arms andstart the motor C in such a direction as to impel the breech upwardly.Similarly if the arm is moved down it will start the motor so as tolower the breech of the gun, and in either case when the properelevation is reached the return of the switch to its central positionstops the motor and the gun at that point. These operations, as will beseen, will all be performed without affecting the motor D in any way.hen, however,.it is required to train the gun and carriage transverselyupon the pivot Z), the arm E is moved to one side or the other accordingto the direction in which the gun is to be moved, and such arm will thenmove freely in the slot '0, but will engage with the slot 0; so as tomove the arm 3 and turn the switch of motor D, so as to start said motorin the right direction; and said motor will be stopped again by bringingarm E back to its normal position.

It will be seen that the position of the gun on its pivot a does notaffect the action of the motor D, and neither does the position 011vertical pivot 11 affect the operation of motor 0.

It will be seen, further, that both motors may be made to run together,whereby the gun will move in an oblique line by moving the arm Eobliquely in the required direction, whereby said arm will engage withboth slots 12 and o and turn both the motor-switches.

' In Fig. 3 the arms 7 and 0" are shown as arranged to operate thevalves or other controlling parts of the fluid-pressure motors.

Fig. 4 shows an arrangement wherein only one motor is employed both forraising and lowering and for horizontally moving the driven body. F isthe motor. Upon its shaft is abevel gear-wheel H, engaging with a wheelH,whose shaft I carries a bevel-gear K. This engages with one face ofthe double gearwheel L, whose other face is adapted to engage witheither of the bevel-gears M and M, according to whether the sleeve 0,which is keyed on the shaft O,is raised or lowered on the shaft. Shaft-O terminates in screw 71, which may operate as described with referenceto Fig. 1.

It should be understood that in Fig. at the controlling apparatus isshown as to be placed on the opposite side of the gun from that 011which it is shown in Fig. 1.

The sleeve 0 is raised and lowered by means of the arm E, universallyhinged at m, as before explained. This arm carries a slotted cross armP, through which the sleeve 0 passes, having a collar on each side ofthe cross-arm. hen the arm E is moved laterally, it does not affect thesleeve 0, since the shaft 0 slides in the slot; but when the arm israised it lifts the sleeve into the posi-. tion shown in the drawings,with the wheel M engaging with wheel L and receiving motion therefrom insuch direction as to raise the breech of the gun; and when the arm E islowered the wheel M engages with L, and by turning the screw in theopposite direction causes the breech of the gun to be lowered. The shaftof motor F also carries a bevel gearwheel Q, which is adapted to engagewith either the wheel R or wheel R, these Wheels being on a shaft S,which slides through a stationary sleeve S. Sleeve S carries a gearwheelT, engaging with a wheel T, which gives motion to the driving-wheel c.

The arm E passes through a vertical slot in the end of a bent pivotedarm U, whose horizontally-extending end is joined to a vertical arm U,which terminates in a collar V, encircling the shaft S between twoflanges on the shaft. It will be seen, therefore, that the verticalmovement of arm E, by which the elevation of the gun is controlled, doesnot affect the shaft S; but a lateral movement of said arm either raisesor lowers the said shaft S and causes either wheel R or wheel R to comeinto engagement with wheel Q, whereby wheel 0 is turned and the drivenbody is propelled in the required direction. The bevel.- gears H II willwork through an opening in the side of the gun-carriage.

It is evident that placing the slot in a crossarm on thecontrolling-lever is mechanically equivalent to placing it in the armmoved by said lever and passing the lever through it.
